iphone - Many UIView animation causing performance problem? -

-

i have object animation... if there many(more 25) objects doing animation @ same time causing jerk while dragging... creating animation using below code in each object. how can improve performance?

#define default_anim_spped 0.6 #define infinate_value 1e100f  - (void)startanimating {     mbackgroundimageview.frame = moriginalframe;     [uiview beginanimations:nil context:nil];      [uiview setanimationrepeatautoreverses:yes];     [uiview setanimationrepeatcount:infinate_value];     [uiview setanimationduration:default_anim_spped];         cgrect tempframe=mbackgroundimageview.frame;     tempframe.origin.y -= manimationoffset;     mbackgroundimageview.frame=tempframe;     [uiview commitanimations]; }

rather creating animation each view, try having 1 animation block animates multiple views, example in common superview. i'm not sure make enough improvement 25 views case.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
